Question

Match the pathway with its most highly regulated enzyme.

Fructose 1,6 biphosphate phosphatase
Glucose-6-phosphate dehydrogenase
Glycogen synthase
Phosphofructokinase 1
Acetyl CoA carboxylase
Carbamoyl phosphate synthetase

A.Glycogenesis
B. Glucogenesis
C.Urea cycle
D.Fatty acid synthesis
E.Glycolysis
F.Pentose phosphate pathway

Answer 1

A.Glycogenesis: Glycogen synthase

B. Glucogenesis: Fructose 1,6 biphosphate phosphatase

C. Urea cycle : Carbamoyl phosphate synthetase

D.Fatty acid synthesis: Acetyl CoA carboxylase

E.Glycolysis : Phosphofructokinase 1

F. Pentose phosphate pathway: Glucose-6-phosphate dehydrogenase

Step-by-step explanation:

A. Glycogen synthase converts glucose into glycogen during glycogenesis.

B. Fructose 1,6 biphosphate phosphatase catalyzes condensation of dihydroxyacetone phosphate (DHAP) and glyceraldehyde-3-phosphate during glucogenesis.

C. Carbamoyl phosphate synthetase I catalyses production of arbamoyl phosphate during urea cycle.

D. Carboxylase controls fatty acid metabolism.

E. The phosphofructokinase 1 is an important enzyme that regulate formation of two-phosphate sugar molecules during glycolysis.

F. Glucose-6-phosphate dehydrogenase participates in the pentose phosphate pathway. This pathway gives reducing energy to cells.
